Solvent/lubricant blends are pretty common, the theory is that the solvent
thins the lube and helps it penetrate tight spots and dissolve gunk , then
the solvent evaporates, leaving the oil behind. WD-40 might be a bit
different than just oil , it really isn't that great a lubricant for
anything that really needs oil or grease, though it is great for some jobs
that just need cleaning/freeing up and then a little bit of lubricity.

Hi,

Have always wondered a bit regarding WD 40.

Apparently it has a "solvent" component, and also some lubricating
oil mixed in.

A solvent and a lubricating oil seem totally contradictory in purpose,
and, to some extent,
even self-cancelling.

But the stuff does, more or less, work.

Anyone explain ?
